A dental cavity in a tooth is the result of the decay process that happens over time when bacteria in the mouth produce acids. In a time, acids can dissolve enamel and cause a hole, which is known as a cavity. Unlike some other injuries, a cavity will not heal by itself and needs to be filled. Several different materials are available, and each material has advantages and disadvantages.
Dental fillings can be categorized as direct or indirect restorations. Direct restorations are fillings that get inserted into a cavity in a single visit. These substances include consisting of amalgams,

The problem is to test, based on the level of mercury, whether the two batches, X and Y, originated from the same catch. The statistical method used to perform this kind of test is the Mann-Whitney U-test.
Mann-Whitney U-test is used to compare whether two independent samples have been drawn from a population with the same characteristics. And it is used only when there are two samples to compare. In case there are two independent samples, Kruskal-Wallis test is used to investigate whether the samples were drawn from the population with similar characteristics.

The following steps would be followed when doing a Mann-Whitney u-test:

- Levels of mercury content in

Introduction

Emission of the toxic substance by industries is common all over the world. Toxic substances are emitted daily by industries and anthropogenic activities. Toxic substances are categorized into three categories namely organic, inorganic and metallic compounds. Examples of organic, inorganic and metallic compounds are methane, sulfate and mercury respectively. There have been reports of these substances having negative effects on the environment. Substances like methane are responsible for increased atmospheric temperature. Sulfates affect soil. Sulfates combine with atmospheric water to form acid water. Acid water has a negative effect of soil and microorganism living in it. Mercury, on the

- The Role of the Doppler effect in determining the rotation rates of both Mercury and Venus
The Doppler Effect describes how waves of any kind move, depending on the direction the source of the waves is moving in and the position of the observer. For example, in the diagram below, the two individuals perceive the siren’s noise differently depending on the length of the wavelength and degree of the frequency, premised on where each person is standing.

The rotational rate of Mercury cannot be determined through optical observation since the planet is comparatively small and is

Block 1: Problems, Challenges and Opportunities (Parts 1 and 2)
T207 Engineering: Mechanics, Materials, Design
Answer 1(a)
The three categories of Engineering Solutions are Innovation by Context, Innovation by Development and finally Routine Solutions. Innovation by Context will have inventions in their ranks, which relies on a new technology to bring about a solution to a problem. The ball point pen(deviating away from the liquid ink), the Gore-Tex® Fabric which is not a fabric but layers of artificial organic material making it breathable, waterproof one-way,durable,etc. and the Dyson™ Vacuum Cleaner which uses cyclonic vacuum technology

1- The chapter opens with these words: “ Neeru, shouei, maima, aqua. In any language, water is the most abundant compound on the surface of the Earth.”
- Explain the term compound and also why water is not an element.
Answer: Compound is a chemical entity made from combination of two or more different elements. These elements lose their individual identities when they combine to form a compound and possess unique properties subjected to that compound. Water is made from two molecules of hydrogen and one molecule of oxygen. Hydrogen and oxygen individually are elements but when combined in the

The James Bay Cree region covers the coast and the drainage systems of Hudson Bay in Canada. It extends from James Bay’s section of Lac Guillaume-Delisle to the Rupert’s Bay. The number of people occupying the area is approximately 12, 000 people. The whole region is under the Quebec government. There are the Coasters (Wiinibeyk Iiyuu) and in land people (Nuuchcimiihc Iiyuu) who are the main occupants of the region. They anciently depended on maritime sea mammals and fur trade for survival respectively. The inland Cree were also small-scale hunters who were in organized groups targeting the

Meissner effect is one of the remarkable properties of superconductors. Most superconductors are metals and metal alloys. However, some non-metals also exhibit superconductive properties hence they are regarded as superconductors. A superconductor refers to a material that can transfer electric current with zero resistance. This implies that when electric current is passed through a superconductor at a temperature below the critical temperature value (Tc), no energy is lost in any form: sound, heat, or light. It is important to point out that superconductivity of a material can only be observed at temperature below the critical temperature (Tc). Critical temperature

The United States and Soviet Union have always seen themselves together in the same sentence because they have always tried to one up the other. This scenario is one that is very real with regards the conquest of outer space. For some reason America seemed to be playing catch up as she was a step behind with regards exploring outer space and putting a man in space
Project Mercury is a program by NASA with an aim to launching the first Americans into space. During the duration of Project Mercury six flights were made by astronauts. Of that six,

Question 1

Mercury is indeed an appropriate acquisition target for AGI because of several reasons. First, the acquisition of Mercury could actually financially improve both companies. Acquiring Mercury would double the revenue of AGI. In spite of the fact that the financial performance of Mercury has been relatively disappointing, the company did however experience a 20% top line growth in the year 2006.
Unfortunately, the two companies have been exhibiting disappointing profitability. This can be attributed to their prices concessions to the industry’s big retailers and also to a women’s line that was quite unsuccessful.
Therefore, the profitability of
